Thanks for the information. I am carrying a P-238 which would be about the same as the tested gun. I have had trouble with normal JHP from several manufacturers diving into the ramp with normal slide release. Discussion with Sig Sauer was typical, "Shoot it more and it will improve." The Pow R Ball 380 70gr (@$1.20/rnd) has fed and extracted perfectly through my gun and three different mags. I am not sure that the heavier FMJ isn't as good for a carry bullet and is much less expensive. I can tell no difference in accuracy or recoil.
